Well as you all read before, I had that rotten eggsmell and my car was slower then a civic. The codes that I had were P0172 and P0175. After going back and forth and doing enormous amount of research, i've ordered a new MAF from DaveB. I changed the MAF, and guess what? YES!!!!! It fixed all the problems. My car shoots out like a bullet now. When I was testing the car out on my block, i took the traction control off, and I floored it........ HOLYYYYY.. the wheels were spinning outta CONTROLLL. It threw me back on my seat and took off quick. Everytime I floor it now, the car jets out FAST.. anyway, I also replaced my ignition coils and spark plugs last week. I guess the complete result is I got my original maxima's promising horsepower back.

I also wanna thank all of you guys that has helped me out, specially Rishi (packetattack), Tony (ant96gle), Chino, Brandon and Dave Burnette. Thanks A LOT man, this problem was driving me CRAZY and I was getting frustrated with this car.
